(a)

Interpretation Introduction

Interpretation: The given set of molecules should be distinguished under given conditions by using IR and mass spectrometer.

Concept Introduction:

IR spectral studies: It is a spectroscopic technique which is used to determine the functional groups present in the given compound sample by absorbing frequency in particular range with respect to the group present in the given sample.

Wavenumber: It is defined as the number of waves in one centimeter. The wavenumber indicates the location of each signal with respect to the functional group in the molecule and its unit is ${\text{cm}}^{\text{-1}}$.

Mass spectroscopy: It is a form of spectroscopic technique which is used for the elucidation of the molecules, depending upon the mass of the molecule.

$\text{M+1}$ peak: It denotes the peak that arises next to molecular ion peak in the mass spectrum. The $\text{M+1}$ peak in mass spectroscopy is used to explain the number of carbon atoms present in molecule. The peak arises due to the presence of the isotope of carbon $\left({}^{\text{13}}\text{C}\right).$

Molecular ion peak: It is defined as the heaviest peak in the IR spectrum of the molecule which represents the largest molecular ion in the given molecule with greater m/z value.

Base peak: It is the tallest peak in the spectrum.
